Description

Technical Field

[0001] The utility model belongs to the technical field of dough skin pressing and cutting machines, and particularly relates to a pressing and cutting knife structure of a dough skin pressing and cutting machine. Background Art

[0002] The dough pressing and cutting machine's cutting blade ensures precise dough cutting, resulting in neat edges and consistent product quality. Through mechanized operation, the cutting blade significantly improves production efficiency, reduces labor costs, and adapts to large-scale production needs.

[0003] Traditionally, the press-cutting blade assembly is fixedly mounted on the dough sheet press-cutting machine. If dough sheets of different shapes need to be cut, the entire press-cutting machine must be replaced or multiple press-cutting machines with different functions must be installed, which limits production flexibility. To meet varying production needs, companies need to invest more money in purchasing multiple machines or frequently replace equipment components. Fixed press-cutting blade assemblies can be more difficult to maintain and clean, potentially impacting the normal operation of the equipment and production efficiency. Replacing press-cutting blade assemblies typically takes a long time, which increases production changeover time and impacts production continuity and efficiency.

[0004] Traditional press cutter assemblies often require tools for disassembly and installation, a cumbersome and time-consuming process that impacts production efficiency. They can also be difficult to adapt to changing cutting requirements, and the complicated process of replacing blades limits the machine's applicability. The difficulty in replacing and adjusting the blade holder also leads to extended machine downtime when the blade becomes worn or damaged, increasing maintenance costs.

[0005] In view of this, we propose a press cutter assembly that tends to be modular and detachable and replaceable to improve production efficiency and flexibility. The press cutter can be quickly replaced according to different production needs, thereby producing dough products of different shapes and sizes. The press cutter structure of the dough pressing machine can solve the merchant problem. Utility Model Content

[0006] The present invention aims to solve the technical problem that the cutting blade assembly of the dough pressing and cutting machine in the prior art cannot be disassembled and replaced at will to produce dough products of different shapes and sizes.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A dough pressing and cutting machine has a cutting blade structure, comprising:

[0009] The descending plate is pushed down by the upward and downward driving shafts of the dough pressing and cutting machine;

[0010] The tool holder is detachably mounted on the bottom of the descending plate. The tool holder includes a mounting plate, two plug-in rods symmetrically arranged on both sides and fixed to the top of the mounting plate and matched with the plug-in seat at the bottom of the descending plate, and a square plug-in slot with a U-shaped opening on the top;

[0011] The threads on the downward plate penetrate two downward screws that are screwed into the positioning grooves of the plug-in rod and push the plug-in rod to tighten and position it in the plug-in seat. The threads at the center of the downward plate penetrate an upward screw that is inserted into the U-shaped opening. The bottom of the upward screw is fixed with a limit block that is movably inserted into the square plug-in slot and limited in the square plug-in slot. The limit block is locked and positioned in the square plug-in slot by rotating the upward screw.

[0012] The U-shaped opening cooperates with the upward screw rod to be plugged into the lower screw rod by turning the lower screw rod downward, screwing the lower screw rod into the positioning groove of the plug rod and pressing the plug rod to be positioned in the plug seat, and then turning the upward screw rod upward to lock the limit block into the square plug groove, thereby completing the installation of the knife holder at the bottom of the descending plate. When disassembling, it is only necessary to turn the lower screw rod upward and downward so that the lower screw rod releases the locking position of the plug rod, and the limit block is also loosened from the relative direction of the plug slot, and the plug rod on the guide is pulled out along the plug seat to complete the disassembly of the knife holder. In this way, the knife holder with different cutting blades can be replaced to meet the different cutting requirements of the dough pressing and cutting machine.

[0013] Preferably, a knob A located above the descending plate is fixed on the top of the downward screw, and a knob B located above the descending plate is fixed on the top of the upward screw.

[0014] Preferably, a docking plate is provided on the top of the descending plate, which is symmetrically arranged front to back and fixedly mounted in conjunction with the driving shaft.

[0015] Preferably, the four corners of the descending plate are provided with guide sleeves A which penetrate the descending plate and slide in conjunction with the guide posts on the frame of the dough pressing and cutting machine.

[0016] Preferably, the blade holder further comprises a pressing plate for pressing the dough on the dough pressing and cutting machine and a pressing and cutting blade fixedly arranged at the bottom of the mounting plate.

[0017] Preferably, the pressing plate is provided with a through hole for the pressing and cutting blade to pass through.

[0018] Preferably, mounting brackets for guide rods are fixed to the top of the four corners of the pressing plate. Four sets of springs are positioned between the mounting brackets and the mounting plate, each of which fits over the outer sides of the guide rods. The combination of the brackets and springs increases the elasticity of the pressing plate when pressing the dough, minimizing damage to the dough.

[0019] Preferably, the mounting plate is provided with a guide sleeve B that fits the guide rod for guiding and sliding, and the descending plate is provided with a guide hole that fits the guide rod for guiding and sliding. The guide sleeve B and the guide hole provide stable guidance and positioning for the tool holder.

[0020] Compared with the prior art, the technical effects and advantages of the present invention are as follows: the cutting knife structure of the dough pressing and cutting machine realizes the detachable installation of the knife holder through the cooperation of two sets of rotating screws and the plug-in mechanism. The descending plate is a part of the dough pressing and cutting machine, which is pushed up and down by the push shaft. The knife holder is designed to be detachable, and its bottom is matched with the plug-in seat at the bottom of the descending plate through two plug-in rods. The plug-in rod is inserted into the limit plug-in hole of the plug-in seat, and the plug-in rod is tightened by the rotation of the downward screw to fix it in the plug-in seat. At the same time, the U-shaped opening at the top of the knife holder cooperates with the upward screw at the center position of the descending plate, and the limit block fixed at the bottom of the upward screw is inserted into the square plug-in groove at the top of the knife holder, and the locking and positioning of the limit block is achieved by the rotation of the upward screw. In this way, the knife holder can be firmly installed at the bottom of the descending plate.

[0021] This design allows for quick removal and replacement of the blade holder, enhancing the dough sheet pressing and cutting machine's adaptability to diverse production needs. Companies can quickly switch to producing dough sheets of varying shapes and sizes based on order requirements. This easy replacement of the blade holder significantly reduces downtime during production, improving efficiency and reducing costs. The removable blade holder facilitates cleaning and maintenance, helping to maintain optimal machine operation and extend its lifespan.

[0022] Compared to requiring multiple dedicated machines, this design allows a single device to perform multiple cutting tasks, saving both equipment investment and operating costs. Operators can install and remove the tool holder with a simple lever rotation, reducing operational difficulty and training costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The following is combined with Figure 1-7 To further explain this application,

[0033] The embodiment of the present application discloses a pressing and cutting blade structure of a dough pressing and cutting machine, comprising a descending plate 100 and a blade holder 200;

[0034] The descending plate 100 is pushed downward by the upward and downward drive shafts of the dough pressing and cutting machine. A docking plate 17 is symmetrically positioned on the top of the descending plate 100 and securely engages the drive shaft. The symmetrical mounting of the docking plate 17 with the drive shaft enhances the stability of the descending plate 100 and helps maintain the precise position of the blade holder 200. The design of the docking plate 17 simplifies the docking of the descending plate 100 with the drive shaft, reducing installation time.

[0035] Guide sleeves A18 are installed at the four corners of the descending plate 100 and slide along the guide posts on the dough pressing and cutting machine frame. These sleeves slide in tandem with the guide posts, providing precise guidance and ensuring smooth movement of the knife holder 200. These sleeves reduce wear from direct contact between the guide posts and the descending plate 100, thereby increasing the lifespan of the machine.

[0036] The blade holder 200 is removably mounted on the bottom of the descending plate 100. It comprises a mounting plate 21, two symmetrically arranged connector rods 22 fixed to the top of the mounting plate 21 and engaging with the connector socket 11 at the bottom of the descending plate 100 for limited insertion, a square connector slot 24 with a U-shaped opening 23 at the top, a pressure plate 26 for pressing the dough on the dough pressing and cutting machine, and a pressure cutting blade 27 fixed to the bottom of the mounting plate 21. The arrangement of the pressure plate 26 and the pressure cutting blade 27 ensures uniform compression of the dough, improving cutting efficiency and accuracy. The pressure plate 26 is provided with a through hole 28 for the insertion of the pressure cutting blade 27. The design of the through hole 28 allows the pressure cutting blade 27 to pass smoothly, ensuring a smooth cutting action.

[0037] The lower plate 100 is threaded with two downward-threaded screws 12 that screw into the positioning slots 25 of the insertion rod 22 and securely hold the insertion rod 22 in place within the socket 11. A top-threaded screw 13 is threaded through the center of the lower plate 100 and inserted into the U-shaped opening 23. A stopper 14 is fixed to the bottom of the top-threaded screw 13, which is inserted into and retained within the square insertion slot 24. The stopper 14 is locked into place within the square insertion slot 24 by rotating the top-threaded screw 13 upward. A knob A15, located above the lower plate 100, is fixed to the top of the downward-threaded screw 12. A knob B16, located above the lower plate 100, is fixed to the top of the top-threaded screw 13. Knobs A15 and B16 are located above the lower plate 100, allowing the operator to manually rotate the screws for quick installation and removal of the tool holder 200. The operator can complete the fixing and disassembly of the tool holder 200 without using additional tools, thereby improving the convenience of operation.

[0038] Mounting blocks 210 for guide rods 29 are fixed to the top corners of the pressing plate 26. Four sets of springs 211 are located between the mounting blocks 210 and the mounting plate 21, each of which fits over the outer sides of the guide rods 29. The combination of the mounting blocks 210 and springs 211 increases the elasticity of the pressing plate 26 when pressing the dough, minimizing damage to the dough. The elasticity of the springs 211 allows the pressing plate 26 to automatically reset after cutting is complete, improving operational continuity.

[0039] The mounting plate 21 is equipped with a guide sleeve B212 that slides through and mates with the guide rod 29. The descending plate 100 is provided with a guide hole 19 that mates with the guide rod 29. The guide sleeve B212 and guide hole 19 provide stable guidance and positioning for the tool holder 200, ensuring stability during the cutting process. The design of the guide sleeve B212 and guide hole 19 reduces direct contact between the guide rod 29 and the mounting plate 21 and descending plate 100, thus reducing wear.

[0040] The cutting knife structure of the dough pressing and cutting machine is as follows: when the knife holder 200 is installed on the descending plate 100, the plug-in rod 22 on the knife holder 200 is limitedly inserted into the plug-in seat 11 at the bottom of the descending plate 100, the square plug-in groove 24 is pushed flat on the outer side of the limit block 14, and the U-shaped opening 23 is plugged in with the upward screw 13. By rotating the downward screw 12 downward, the downward screw 12 is screwed into the positioning groove 25 of the plug-in rod 22 and the plug-in rod 22 is tightly positioned in the plug-in seat 11, and the upward screw 13 is rotated to lock the limit block 14 in place. The square plug-in slot 24 completes the secure installation of the knife holder 200 at the bottom of the descending plate 100. When disassembling, it is only necessary to rotate the lower screw 12 upwards and downwards to release the locking position of the lower screw 12 on the plug-in rod 22, and the limit block 14 is also loosened relative to the plug-in slot, and the plug-in rod 22 on the guide is pulled out along the plug-in seat 11 to complete the disassembly of the knife holder 200. In this way, the knife holder 200 with different cutting blades 27 can be replaced to meet different cutting requirements of the dough pressing and cutting machine.

[0041] Since the blade holder 200 can be quickly disassembled and installed, it becomes convenient and quick to replace the blade according to different cutting requirements, greatly improving production efficiency. Through the limiting cooperation of the plug-in rod 22 and the plug-in seat 11, and the locking of the upward screw 13 and the limit block 14, the accurate positioning of the blade holder 200 can be ensured, thereby ensuring the accuracy of cutting. This structural design allows the dough pressing and cutting machine to be suitable for different cutting tasks, and only the corresponding blade holder 200 needs to be replaced, thereby enhancing the applicability and flexibility of the machine. Since the connection between the blade holder 200 and the descending plate 100 is through mechanical locking rather than manual fixation, it is safer during operation and reduces safety accidents caused by improper operation. The quick replacement and accurate positioning of the blade holder 200 reduces machine downtime caused by blade wear or damage, thereby reducing maintenance costs. Since the blade holder 200 is easy to disassemble and install, daily maintenance and cleaning of the machine also become easier.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
